如何将两个或多个字符的十六进制值相加？

def hex_addition(hex1, hex2):
    # 将十六进制字符串转换为十进制值
    dec1 = int(hex1, 16)
    dec2 = int(hex2, 16)
    
    # 相加得到结果
    result = dec1 + dec2
    
    # 进位处理
    carry = result // 16
    remainder = result % 16
    
    # 将结果转换为十六进制表示
    hex_result = hex(remainder)[2:].upper()
    
    # 如果有进位，则加到下一个字符的十进制值上
    if carry > 0:
        hex_result = hex_addition(hex_result, hex(carry)[2:].upper())
    
    return hex_result

# 示例使用
hex1 = "A1"
hex2 = "2F"
result = hex_addition(hex1, hex2)
print(result)  # 输出：D0
